HEATING APPARATUS FOR BARRELS.

Specification of Letters Patent.

Patented Jan. 11, 1910.

Application filed May 13, 1909. Serial No. 495,634.

To all whom "it may concern:

Be it known that I, HENRY F. MARTEN, a citizen of the United States, residing in-the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Heating Apparatus for Barrels, of which the following is a specification.

The hereinafter described invention rclates to an apparatus for heating barrels interiorly and exteriorly in order to set or fix the shape as to the wooden staves thereof, and the object thereof is the providing of a simple, inexpensive, and eflicient apparatus for the heating of a plurality of barrels at one operation from a common source of heat supply, so as to reduce the expense incident to the heating of the barrels, increase the capacity of the heating plant, and give to the barrels a uniform degree of heat.

To comprehend the invention, reference should be had to the accompanying sheet of drawings, wherein- Figure 1 is a front elevation of the furnace with its door removed, said view illustrating the superstructure or frame arranged above the furnace for supporting the hoods for the barrel, a barrel fitted over one of the heat outlets of the furnace, and the hood for inclosing the barrel suspended above the same. Fig. 2 is a broken side elevation of the apparatus, the furnace being in longitudinal section, a plurality of barrels being illustrated in position, and a plurality of hoods for the barrels, one of said hoods being shown in lowered position and inclosing a barrel.

In the drawings, the numeral 1 is used to designate the outer shell or wall of the longitudinally disposed furnace, which preferably is composed of ordinary bricks, and 2 an inner lining therefor formed of firebricks. The outer or forward end portion of the furnace is provided with a combustion chamber 3, within which is fitted a grate bar 4, for the holding of loose brick onto which impinges the flame from the oil burner 5, located within the combustion chamber 3. This chamber communicates with the rearwardly extended heat receiving chamber 6, into which the heated atmosphere from the combustion chamber flows. Air for supplying oxygen to the oil burner, is preferably admitted into the combustion chamber 3 from below the grate bar 4, but such is an immaterial detail.

Above the furnace is arranged a superstructure comprising a series of vertically extended guide-ways 7, formed by means of the skeleton frame 8, within which guideways work the cylindrical metal hoods 9, which hoods are of a size to fit over and inclose a barrel 10. The weight of each hood is counter-balanced by means of a weight 11, each weight being secured to the free end of a cable or chain 12, working over pulley 13 arranged in the upper portion of the guide-way within which the hood 9 suspended from the opposite end of the supporting cable or chain 12 works. By this means, the hood is balanced, so that the same may be easily raised and lowered relative to the barrel 9, placed within its guideway 7.

Through the top of the furnace is formed a series of outlets 1 1, each of which communicates with the interior of the furnace, and the said outlets are so arranged that one is provided for each of the guide-ways 7, and centrally thereof. These heat outlets 14; are closed by the cover plates 15, which, when fitted over the said outlets, prevent the escape of heat from within the furnace.

When it is desired to dry or heat one or more barrels, the cover plate 15 of the respective outlet-s 14 is removed and the barrel 10 placed directly thereover. The hood 9 is then lowered to inclose the said barrel, when the heat from the furnace ascends through the opened outlet and passes into the interior of the barrel, escaping therefrom to the outside to thoroughly heat or dry the barrel, the heat circulating through the barrel being confined by means of the inclosing hood fitted thereover. After having subjected the barrel to the action of the escaping heat sufliciently long to thoroughly dry the same, to set the staves, the hood is raised and the barrel removed from within the guide for the vertically movable hood, to make room for a fresh barrel to be heated, or the outlet may be closed against the escape of heat by placing thereover the cover plate 15.

The described apparatus permits of a plurality of barrels being heated at the same time from a common source of supply, and

the heat applied at substantially a uniform temperature to all of the barrels. By thus providing for treating a plurality of barrels at the same time, from a common source of supply, the expense incident to the heating and handling of the barrels is materially reduced, and the output of the heating plant. augmented. Again, the barrels are heated uniformly, resulting in an even treatment of the barrels. By the utilization of oil as the heating medium, the furnace may be maintained at relatively the same degree of heat, after the initial heating, throughout the entire working thereof, so that the exposure of the barrels for proper heating may be readily determined. A simple, effective and expeditious apparatus for the heating of a plurality of barrels at one operation is thus produced, and the expense incident thereto reduced to a mini mum.

Having thus described the invention, what is claimed as new and desired to be protected by Letters Patent is 1. An apparatus for the described purpose, the same comprising a longitudinally disposed furnace provided with a combustion chamber and a heat circulating chamber communicating therewlth, a plurality of controlled heat outlets leading from the furnace, each of which outlets is controlled in l dependently of the others, a plurality of vertically movable cover hoods arranged above the heat outlets one for each outlet to inclose barrels placed thereover and a liquid fuel burner located within the combustion chamber of the furnace, and at a point removed from said outlets.

2. An apparatus for the described purpose, the same comprising a longitudinally disposed furnace provided with a combustion chamber and a continuous unobstructed heat circulating chamber communicating therewith, independently controlled heatoutlets leading from the heated air chamber, means for inclosing a barrel placed over each outlet, and a liquid fuel burnerlocated within the combustion chamber of the furnace.

8. An apparatus for the described purpose, the same comprising a longitudinally disposed furnace provided at one end with a combustion chamber, and a heat circulating chamber communicating with said combustion chamber the same being continuous and unobstructed whereby will be provided substantially uniform heatin said circulating chamber throughout, spaced openings in the top Wall of the circulating chamber, an independent closure for each of said openings located on said top wall, vertical rods mounted on said top wall of the circulating chamber, one upon opposite sides of each opening and vertically movable cover hoods arranged above the openings in the top wall of the circulating chamber, said hoods having guides slidably mounted on said vertical rods, and a liquid fuel burner in the combustion chamber having an outlet forwardly of all of the openings in the top of the circulating chamber.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
